       1. A computer comprising:
 a memory configured to store an item group including a plurality of types of items with different scarcity values; and 
 circuitry configured to,
 provide, to a user, at least one item of the item group, 
 store, in the memory, a provision count of the number of times any item of the plurality of types of items is provided to the user, 
 provide, to the user, a first additional item based on the stored provision count, wherein 
 when a predetermined condition is satisfied, further provide, to the user, a second additional item, in addition to the provided at least one item, based on the stored provision count. 
 
 
     
     
       2. The computer according to  claim 1 , wherein
 the first additional item has a higher scarcity value than any item in the item group. 
 
     
     
       3. The computer according to  claim 1 , wherein
 the circuitry further configured to provide the first additional item to the user by including the first additional item in the item group when (i) the stored provision count reaches a predetermined count, and (ii) a time since the stored provision count reached the predetermined count is within a predetermined time. 
 
     
     
       4. The computer according to  claim 1 , wherein
 the circuitry further configured to transmit information on the provision count to a communication terminal of the user. 
 
     
     
       5. The computer according to  claim 1 , wherein
 the circuitry further configured to provide the second item to the user in accordance with the item that is drawn from among the item group. 
 
     
     
       6. The computer according to  claim 1 , wherein
 as the item provision count becomes higher, the scarcity value of the second item that is provided becomes higher. 
 
     
     
       7. The computer according to  claim 1 , wherein
 the circuitry further configured to transmit information for displaying the first additional item or the second additional item to a communication terminal of the user. 
 
     
     
       8. A method for controlling a computer, the computer including a memory, and circuitry, the method comprising:
 storing, in the memory, an item group including a plurality of types of items with different scarcity values; 
 providing, to a user, at least one item of the item group by the circuitry; 
 storing, in the memory, a provision count of the number of times any item of the plurality of types of items is provided to the user; 
 providing, to the user, a first additional item based on the stored provision count by the circuitry; and 
 when a predetermined condition is satisfied, further providing, to the user, a second additional item, in addition to the provided at least one item, based on the stored provision count. 
 
     
     
       9. The method according to  claim 8 , wherein
 the first additional item has a higher scarcity value than any item in the item group. 
 
     
     
       10. The method according to  claim 8 , further comprising:
 providing the first additional item to the user by including the first additional item in the item group by the circuitry, when (i) the stored provision count reaches a predetermined count, and (ii) a time since the stored provision count reached the predetermined count is within a predetermined time. 
 
     
     
       11. The method according to  claim 8 , further comprising:
 transmitting information on the provision count to a communication terminal of the user by the circuitry. 
 
     
     
       12. The method according to  claim 8 , further comprising:
 providing the second item to the user in accordance with the item that is drawn from among the item group by the circuitry. 
 
     
     
       13. The method according to  claim 8 , wherein
 as the item provision count becomes higher, the scarcity value of the second item that is provided becomes higher. 
 
     
     
       14. The method according to  claim 8 , further comprising:
 transmitting information for displaying the first additional item or the second additional item to a communication terminal of the user by the circuitry. 
 
     
     
       15. A non-transitory computer readable recording medium having recorded thereon a program for a computer including a memory, the program causing the computer to execute a process, the process comprising:
 storing, in the memory, an item group including a plurality of types of items with different scarcity values; 
 providing, to a user, at least one item of the item group; 
 storing, in the memory, a provision count of the number of times any item of the plurality of types of items is provided to the user; 
 providing, to the user, a first additional item based on the stored provision count; and 
 when a predetermined condition is satisfied, further providing, to the user, a second additional item, in addition to the provided at least one item, based on the stored provision count. 
 
     
     
       16. The non-transitory computer readable recording medium according to  claim 15 , wherein
 the first additional item has a higher scarcity value than any item in the item group. 
 
     
     
       17. The non-transitory computer readable recording medium according to  claim 15 , the process further comprising:
 providing the first additional item to the user by including the first additional item in the item group, when (i) the stored provision count reaches a predetermined count, and (ii) a time since the stored provision count reached the predetermined count is within a predetermined time. 
 
     
     
       18. The non-transitory computer readable recording medium according to  claim 15 , the process further comprising:
 transmitting information on the provision count to a communication terminal of the user. 
 
     
     
       19. The non-transitory computer readable recording medium according to  claim 15 , the process further comprising:
 providing the second item to the user in accordance with the item that is drawn from among the item group. 
 
     
     
       20. The non-transitory computer readable recording medium according to  claim 15 , wherein
 as the item provision count becomes higher, the scarcity value of the second item that is provided becomes higher. 
 
     
     
       21. The non-transitory computer readable recording medium according to  claim 15 , the process further comprising:
 transmitting information for displaying the first additional item or the second additional item to a communication terminal of the user.
